Need help to handle javascript confirmation alert of next page in selenium ide.

i am automating one site which has following scenario. On page there is Submit button on clicking its redirect to 'next page' and on opening of that getting java script alert message with 'Ok' button. On clicking of Ok button next page details are gettingdisplayed.

my script is getting failed as its unable to find that javascript alert.

I tried with chooseOkOnNextConfirmation and assertConfirmation also assertAlert commands but nothing is working.

getting error as 'There were no alerts' and my script is failing.

I am able to handle javascript alert if its on same page with above commands but not on next page, please help if anybody has done this before.
